Ipv6 address space allocation
WebThere are over a billion IPv6 addresses in use in Australia, and Japan alone, that is over 1/4 of the addresses in ip v4 space. This is the main reason, why we have any IPv4 addresses available for allocation. IPv4 and IPv6 can coexist together. No reason to disable IPv4, some places don't have hardware or software that supports IPv6. WebThe IPv6 address space is big. Really really big. A /64 is generally the smallest subnet in use. A single /64 has way way more IP addresses than all the IPv4 addresses put together. That is why you won’t really ever have to worry about host numbers in IPv6 subnetting. This means that the smallest recommended allocation for a subnet is a /64.

WebIPv6 defines unique local addresses in RFC 4193, providing a very large private address space from which each organization can randomly or pseudo-randomly allocate a 40-bit prefix, each of which allows 65536 organizational subnets. WebAs the Internet transitions to IPv6, the plan for distributed allocation and assignment of the IPv4 address space established in RFC1466 forms a base for the distributed allocation and assignment of the IPv6 address space. The Internet Assigned Number Authority (IANA) is the principal registry for the IPv6 address space.
